I

In the embodiment of the invention shown I in Figs.6, 7, 8 and 9,' the seat portion comprises a plurality'of strips or hands of fabric 40eXtending from side to side" so that the; seat is flexible. o s I Y The ends of the fabric strips 40 are first directly attached to clamping strips 42 which are provided with bars 43 extendingthrough 7 them.

The seat is suppoi tedby' two supporting link frames 41, theside members of which may be parallel, as shown in the drawings.

These link frames are pivoted at their lower: 7 j ends to a plate 46 at the upper end of a supporting columnor-post '47. As" this portion ot the'construction' is similar totheyform.

7 shown in Figs. 1, 2, 3 and 4', further description is thought to be unnecessary. At the upper or free end of each link frame 41is pivotally mounted'an extensionlink 48, the

side members of which may be parallel, and having end members and-49. fvThe side Y When .itllelegmembers 1 care in their ex} q tended-position; To close thi-leg members to carryingfposition, it "is only necessary to members have hooks 54 at their outer ends.

' attached. 7 These extension links 48 arepiV otally attached to the link frames 41 by" the members 49'. and, are adapted to vbe held in their extended position by movable rods 50' i slidably movablein. slots in'the side members either in alignment withthe link fr'ames 41' of the links 48. The rods 50 are adapted to engage notches 51 on-the outer ends of the side members of the link frames 41- so that ineansgfor holding said seat extended, means 7 forholdingsaid tripod legs extendedymeans I "for holding said-link framesextended5'and means-forlholding said backIeXtended, alli Q the extension links 48 may be supported or atdiiierent angles thereto. a V V In ordergto set up the chair or'stocl in its operative or unfoldedarrangement, the link frames 41 are moved to their oblique up wardly extending positions and both of the clamping strip bars 43 are engaged under the hookedportions 54 on the links 48, One of the extension links 48 is made fast by engaging its sliding rod 50 inthe notches 5101f seat, the Eside members of each oneof said"- link framesbeingeparallel;a back formed in 1 parts on as tobe fold'able on itself andpivoted; to; tone offlsaid link frames; means'lzfor'f one of the link frames 41, and then theother extension link 48 is made tight by engaging a similar sliding rod. 50in the notches 51in the other linkframe 41.
